In August 1901, Bonfanti performed with Rita Sangalli at the Metropolitan Opera House, during the inaugural season of ballet at the New York City venue.
Her talent for expressionist dancing and her private life were covered widely from the mid-1860s until the early 20th century.
Among her students (for a short period of time) were Ruth Saint Denis and Isadora Duncan.
Bonfanti was born in Italy.
She was married to George Hoffman, whose father George I.
Hoffman, was sued by Jay Cooke, McCullough & Co., in the New York Supreme Court in Brooklyn, New York, in December 1876.
The court proceedings dealt with a loan of $3,300 made to the younger Hoffman by his father.
